CITY COUNCIL WORK SESSION DRAFT 2 - Review of existing ditch system (on map) and summary of drainage plans; 42 - Council action requested and advisory board actions and public comments. 43 Mayor Rafferty asked about the 2-1 vote of the Planning and Zoning Board. Ms. Larsen 44 noted that the board is at 5 members and 2 were absent. Ms. Larsen said the nay voter 45 didn’t make specific comments. 46 47 Mayor Rafferty noted the NE corner and the possibility of the culvert. Is staff concerned 48 that the culvert wasn’t possible due to an easement situation. Ms. Hankee explained the 49 plunge pool dissipater and, after review, staff doesn’t have concerns about the design. 50 Council Member Stoesz asked about the width of the road and how it compares to 51 NorthPoine roadways; will there be any parking restrictions? Ms. Hankee noted that 52 nearby Red Oak has a landscaped median but that is not planned for this development. 53 Staff has ensured that streets will align. Ms. Hankee also noted traffic restrictions that 54 will be included. There will be no parking in the area of the turn lanes. Ms. Larsen added 55 that the roads in general are 32’ wide and here is no variance planned for this 56 development. 57 Council Member Lyden noted that there are legitimate concerns that need to be heard. 58 There are eight total acres being drained by rocks to a ditch. It bothers him that it will be 59 drained to a private ditch and therefore some responsibility falls to the owner of that ditch. 60 He has looked at elevations in the area and how that will drain. He hears engineers speak 61 about rate of drain but he prefers to discuss volume. This involves a field and it’s 62 important to consider the volume of water proposed and the distance over which the drop 63 will occur. Considering those elements, this should be a drop of about eleven feet rather 64 than close to one foot. If that property was to flood, it’s private property so it would be 65 the owner’s responsibility. He has other concerns as well. 66 Mayor Rafferty asked about the source of Mr. Lyden’s technical information. 67 Councilmember Lyden noted the information is based on what he believes is an engineer’s 68 standard. 69 Linda Broussard and David Vickers, own and live on the farm west of the 70 development. Ms. Broussard asked the City Engineer if she is aware of the holding 71 volume of the pond. She’s noted that the original plan called for a deeper and smaller 72 pond. Total square footage was increased in the new ponds. Another question she has, 73 looking at the 2030 Comprehensive Plan, she believes their acreage is supposed to be 74 staged for sewer in 2030 (they own all of the property on the western side of the proposed 75 development). Their primary concern is to lose production in the field (due to water) and 76 additional cost to them if there is erosion. They have about 40 or 50 feet where the water 77 flows over the ground and over years the pond will not stay the same depth; pond cleaning 78 is very expensive and a difference will impact water on their property. While the water 79 naturally flows to their property, currently it comes from a large area rather than the 80 proposed ditch. 81 82
